Quote:<br>
The hand has 20 independently controlled active joints, enabling more<br>
precise and human-like finger movements through its direct-drive<br>
design.<br>
The robotic hand precisely manipulates the thin cards and small coin,<br>
coordinating its independently controlled fingers to execute each<br>
movement. The demonstrations highlight the O30’s ability to perform<br>
delicate object handling and rapid, coordinated finger movements,<br>
showcasing the fine motor control needed for more complex human-like<br>
manipulation tasks.<br>
